The current bitcoin price is $ 3100, and I think it's a good moment to buy, I'm sure next week the bitcoin price will return to $ 4000 and next month's start will reach $ 5000.
I'll wait for that time before I will trade my bitcoin. How can we know accurately updated price of bitcoin cause time by time the price is change. Could someone tell me where site I can be updated for the changing price of bitcoins?
